I have heard that magnesium perchlorate is an extremely good drying agent, but I can't find any chemistry book references on ways of making it.
Is Mg(CLO4)2 made the same way as potassium perchlorate is made, by heating potassium chlorate ?
Anybody got any good text book synths for me while I'll plough though the patent office site ?
One day I'll understand everything !

Couldn't you use ion exchange between MgSO4 and NaClO4?
NaX exchanges with lots of sulfates.

would the sodium perchlorate not oxidise the Magnesium sulphate to a persulphate ?
Oh no that does not balance !
Yes seems a great method !

Is magnesium perchlorate a powerfull enough dehydrator to pull H2O's away from organic chemicals, like turning amide's into nitriles ?
One day I'll understand everything !

Still going for acetamide --> acetonitrile?
I don't know on the MgClO4. What about phthalic anhydride?

You can make P2O5 by heating a phosphate salt with sand (no carbon).

No I'm not going for acetonitrile, I just used it as an example.
Just wanted to know just how powerfull a dehydrating agent magnesium perchlorate is.
One day I'll understand everything !

>How hot?
Very hot. From what I can remember from reading about it, about the same temperatures as making phosphorus.

Don't use magnesium perchlorate as a drying agent. Organic materials in contact with magnesium perchlorate will spontaneously combust. Magnesium perchlorate is used as a drying agent only in a special case - the absorption train of an elemental analysis rig.
